Originally designed to be a 42,000-seat stadium, there were slight modifications before the final design was complete. When the ballpark was brought to the ballot box in the fall of 1996 for voter approval, the stadium was 15° clockwise from its current position. Also the center-field scoreboard was atop the right-field wall and the Giants Pavilion Building were two separate buildings.[10]
Groundbreaking on the ballpark began on December 11, 1997, in the industrial waterfront area of San Francisco known as China Basin in the up-and-coming neighborhoods of South Beach and Mission Bay. The stadium cost $357 million to build and supplanted the Giants' former home, Candlestick Park, a multi-use stadium in southeastern San Francisco that was also home to the National Football League's San Francisco 49ers until 2014, when they relocated to Levi's Stadium in Santa Clara. A team of engineers from UC Davis was consulted in the design process of the park, resulting in wind levels that are approximately half those at Candlestick. Fans had shivered through 40 seasons at "The 'Stick" and looked forward to warmer temperatures at the new ballpark.[11] But because Oracle Park, like its predecessor, is built right on San Francisco Bay, cold summer fog and winter jackets in July are still not unusual at Giants games, despite the higher average temperature.

When it opened on March 31, 2000, the ballpark was the first Major League Baseball ballpark built without public funds since the completion of Dodger Stadium in 1962.[12] However, the Giants did receive a $10 million tax abatement from the city and $80 million for upgrades to the local infrastructure (including a connection to the Muni Metro).[13] The Giants have a 66-year lease on the 12.5-acre (51,000 m2) ballpark site, paying $1.2 million in rent annually to the San Francisco Port Commission.[12] The park opened with a seating capacity of 40,800, but this has increased over time as seats have been added.

In April 2010, the stadium became the first MLB ballpark to receive LEED Silver Certification for Existing Buildings, Operations and Maintenance.[14]

On April 3, 1996, Pacific Bell, a telephone company serving California based in San Francisco, purchased the naming rights for the planned ballpark for $50 million for 24 years. The stadium was named Pacific Bell Park, or Pac Bell Park for short.[15]

Just days before the sponsorship was announced, SBC Communications had announced their intention to acquire Pacific Bell's parent company, Pacific Telesis, a deal which closed in April 1997. SBC eventually stopped using the Pacific Bell name for marketing, and reached an agreement with the Giants to change the stadium's name to SBC Park on January 1, 2004.[15]

After SBC bought AT&T Corporation on November 18, 2005, the name of the merged company became AT&T Inc. As a result, in 2006 the stadium was given its third name in six years: AT&T Park.[15]

On January 9, 2019, it was reported that AT&T had given the Giants the option of ending the naming deal a year early, if the team could quickly find a new partner.[16] The Giants and Oracle Corporation came to a rapid agreement, with the old AT&T Park signs being replaced with temporary Oracle Park banners on January 10.[17]

Some fans still refer to the stadium as Pac Bell Park, as it was the first name given to the stadium. Others have nicknamed the stadium "The Phone Booth" or "Telephone Park", in response to its multiple name changes, while some referred to the stadium as "Some Big Corporation Park" during the SBC years. Others yet refer to it as "Mays Field" in honor of Giants great Willie Mays or simply "The Bell".[18] Many also refer to the stadium as "China Basin" or "McCovey Cove" after its location, which would be immune to changes in sponsorship naming.[citation needed]

Oracle Park has a reputation of being a pitcher's park and the most pitcher-friendly ballpark in the National League, because the depth of the outfield limits home runs, according to ESPN.[19] ESPN's MLB Park Factors lists Oracle Park as having the fewest home runs per game 6 out of the past 7 years, the one exception coming in 2013, when it was the 3rd lowest.

In 2014, PETA declared the park to be the Most Vegetarian-Friendly MLB ballpark in the country. It held the top spot on the same list in 2011, 2006 and 2005.[20]

The most prominent feature of the ballpark is the right-field wall, which is 24 feet (7.3 m) high in honor of former Giants Willie Mays, who wore number 24. Because of the proximity to the San Francisco Bay, the right-field foul pole is only 309 feet (94 m) from home plate. The wall is made of brick, with fenced-off archways opening to the Cove beyond, above which are several rows of arcade seating. The fence angles quickly away from home plate; right-center field extends out to 421 feet (128 m) from home plate. Atop the fence are four pillars with fountains atop. Jets of water burst from the four pillars at the end of the National Anthem and also when the Giants hit a home run or win a game.

The 50 "Splash Hit" counter

In the past, rubber chickens put up by fans whenever a Giants player (especially Barry Bonds) was intentionally walked, would line the foul portion of the wall. The fans would do this to show that the opposing team is "chicken" for not pitching right to the Giants players. In recent seasons, as the team's strength has shifted from hitting to pitching, fans will line up "K" signs with each strikeout by a Giants pitcher. The right field area was designed to resemble the Polo Grounds. This deep corner of the ballpark has been dubbed "Death Valley" and "Triples Alley." Like its Polo Grounds counterpart, it is very difficult to hit a home run to this area, and a batted ball that finds its way into this corner often results in a triple. It is 421 feet (128 m).[21] Triples Alley is also infamous for bad bounces, most notably when Ichiro Suzuki hit the first-ever inside-the-park home run in an All-Star Game by lining the ball off one of the archways and sideways past the outfielders. Nate Schierholtz performed the same feat in the 2009 season as a pinch hitter. Aubrey Huff did it again in the 2010 season, as did Conor Gillaspie in 2011. Ángel Pagán ended a game in May 2013 with a two-run walk-off inside-the-park home run, the first of its kind at the then-named AT&T Park.

Behind the scoreboard in center field there is a pier where ferries can tie up and let off fans right at the park. On game days, fans take to the water of McCovey Cove in boats and even in kayaks, often with fishing nets in the hope of collecting a home run ball. (This echoes what used to happen during McCovey's playing days. Before Candlestick Park's upper deck was extended, the area behind right field was occupied by three small bleacher sections and a lot of open space. Kids in those bleachers would gather behind the right field fence when "Stretch" would come to the plate.) Just beyond the wall behind the ballpark is a public waterfront promenade. Across the cove from the ballpark is McCovey Point and China Basin Park, featuring monuments to past Giants legends.

When the park opened in 2000, taking residence on the right field wall was Rusty, the Mechanical Man based on a theme of Old Navy since the wall was sponsored by the company. Rusty was a two-dimensional robotic ballplayer that stood 14 feet (4.3 m) tall and weighed 5½ tons. The Valencia-based firm, Technifex, engineered, fabricated and programmed Rusty to appear after major plays, during games, as a fully animated giant 1920s-era tin "toy". After technical problems arose with Rusty, it was removed from the Old Navy Splash Landing, though the enclosure that housed him remained for years. In 2006 the Old Navy sponsorship of the wall was terminated and renamed "Levi's Landing". In 2008, the enclosure was removed as that area near the right field foul pole was renovated for a new luxury party suite called the "McCovey Cove Loft".[23]

Behind the left field bleachers is "The Coca-Cola Fan Lot". The ballpark features an 80-foot (24 m) long Coca-Cola bottle with playground slides that lights up with every Giants home run, and a miniature version of the stadium. "The Coca-Cola Superslide" is popular with children as is with adults, and the terraced levels of the slides are a fun way to catch the game. Bubbles originally accompanied the bottle, but never worked as intended and were removed. If one were viewing the outfield promenade from home plate, directly to the bottle's right is another oversized representation of a ballpark stalwart, the "Giant 1927 Old-Time Four-Fingered Baseball Glove" — this particular one is made of steel and fiberglass. Behind and farther to the left is "The Little Giants Park" – a miniature baseball diamond — sort of a minor league tryout for Pee-Wee Ball.[24]

To the right of the glove sculpture is the elevator and large plaza area for functions and parties to be held during games. It's also the site of "Orlando's", the concessions stand of Giants great Orlando Cepeda. The signature fare at the stand is the "Caribbean Cha Cha Bowl". Right-center field features a real San Francisco cable car numbered 44 (retired cable car #4, formerly #504) in honor of Giants great Willie McCovey. Originally, the cable car had a label that stated "No Dodgers Fans Allowed", as well as one end of the car numbered 24 in honor of Willie Mays and the other end numbered 44 in honor of Willie McCovey.[25] The foghorn — a feature introduced at Candlestick Park by the current Giants ownership group – was transferred to Oracle and hung underneath the scoreboard. It blows when a Giants player hits a home run or at the conclusion of a Giants win. Continuing right takes one to the promenade above the Cove, so that one can make a completely uninterrupted circuit of the park at that concourse level. Both levels of the concourse, inside the stadium, feature not only concession stands of all sorts, but other attractions as well.

Located behind the centerfield bleachers, the ballpark features the @Café,[26] a social media café, which opened in the 2013 season. The cafe serves Peet's Coffee and features large screens that show off fans' social media posts from Facebook, Twitter, and Instagram, which are curated by the Giants organization.

In addition to the automated scoreboards, which now[when?] include a new high-definition video board by Mitsubishi, the park has enormous manually-operated boards on the right field wall, which display the scores of Major League games being played elsewhere. The manual scoreboards are operated by three employees, whose work on game days starts at least two hours before the first pitch. A members-only bar, Gotham Club, is located behind the manual scoreboard, complete with a bowling alley and pool tables. Former players and VIPs are the only patrons of this exclusive area.

On September 23, 2008, the Giants Wall of Fame was unveiled on the King Street side of the ballpark,[28] as part of the 50th-anniversary celebration of the Giants' move to San Francisco. 48 retired players were inducted, based on longevity and achievement.[29] Eligibility requirements for players to be on the Wall are either five years as a San Francisco Giant with an All-Star Game appearance or nine years as a Giant.[30] Rich Aurilia and Shawn Estes were added in 2010.[31] Jason Schmidt and Marvin Benard were added in 2011, and Barry Bonds was added in 2017.[32]

Outside the ballpark are six statues, five of which are dedicated to San Francisco Giants all-time greats.

The Willie Mays Statue is located in front of the ballpark entrance at 24 Willie Mays Plaza and is surrounded with 24 palm trees, in honor of his number 24 uniform, retired by the Giants. It was dedicated at noon on March 31, 2000, prior to the opening of the ballpark and was commissioned by Giants Managing Partner Peter Magowan and his wife Debby.[34]

Another statue is located at McCovey Point across McCovey Cove, and is dedicated to Willie McCovey. Around the Willie McCovey Statue are a number of plaques that celebrate the winners of the Willie Mac Award. The statue is located at China Basin Park next to The Barry Bonds Junior Giants Field, a T-ball park. Also located on the sea wall promenade are plaques showing the Opening Day roster of every Giants team from 1958 through 1999. Giants fans who contributed funds to China Basin Park, had their own tiles with their own inscriptions set into the wall.[35]

A third statue, dedicated in 2005, honors former Giants pitcher Juan Marichal, and is located outside the ballpark at the Lefty O'Doul Gate entrance. The fourth statue is located at the park's ferry plaza behind center field, also known as Seals Plaza; a statue of a seal bobbing a baseball on its nose honors the memory of the San Francisco Seals, the minor league baseball club that played before the arrival of the Giants in 1958.

On September 6, 2008, during a series against the Pittsburgh Pirates, a fifth statue depicting former Giants great Orlando Cepeda was dedicated at the corner of 2nd and King Streets next to the ballpark. A sixth statue, dedicated on August 13, 2016, honors former Giants pitcher Gaylord Perry and is also located at the corner of 2nd and King Streets next to the ballpark. All five statues of the Giants Hall of Fame players were created by sculptor William Behrends of North Carolina.

A feature of the ballpark is the long-running Chevron advertisement, located in left field, featuring an outline of the company's claymation Chevron Cars, though the top 'roofs' of the cars (along with a dog and a surfboard hanging out a car window) are extended out (though with traditional structure and cushioning behind it),[36] rendering it several inches higher than the wall base, and creating a ground rules issue. Several instances where potential over-the-wall catches to take away home runs were thwarted have occurred because of the advertisement's top dimensions: for example, during Game 3 of the 2016 NLDS against the Chicago Cubs, Kris Bryant hit a ball well into left field. Giants left fielder Gregor Blanco attempted a catch, but the ball landed on the roof of one of the cars, past the wall and out of his reach, rendering it a home run and tying the game in the top of the ninth inning (though the Giants would win the game in extra innings for their only win in the series).[37] There are also apocryphal stories of Giant players jokingly saying they would saw the tops of the Chevron cars off if they resulted in opposing home runs being unable to be caught.

The opening series took place April 11–13, 2000 against the Los Angeles Dodgers (the team the Giants faced in their final series at Candlestick Park), and the Giants were swept in three games. In the first game of that series, the Giants lost 6–5, highlighted by three home runs from the Dodgers' Kevin Elster. On May 1, 2000, Barry Bonds became the first player to hit a "splash hit" home run into McCovey Cove.

In just its first few years of existence, the ballpark saw its share of historic events primarily due to veteran Giants outfielder Barry Bonds. On April 17, 2001, Bonds hit his 500th career home run at then-Pacific Bell Park. Later that year, he set the single season home run record when he hit home runs number 71, 72, and 73 over the weekend of October 5 to close the season. On August 9, 2002, Bonds hit his 600th career home run at the park. On April 12, 2004, Bonds hit career home run 660 at SBC Park to tie Willie Mays for third on the all-time list and on the next night, he hit number 661 to move into sole possession of third place. On September 17, 2004, Bonds hit his 700th career home run at the park to become just the third member of baseball's 700 club. On May 28, 2006, Bonds hit his 715th home run at the park to pass Babe Ruth for second place on the all-time list. On August 7, 2007, Bonds hit his 756th home run, breaking Hank Aaron's record.

On October 27 & 28, 2010, the Giants hosted the first two games of the World Series, beating the Texas Rangers in both games. They ultimately went on to win the series, their first championship since the team moved to San Francisco in 1958, though the clinching game was played at Rangers Ballpark in Arlington rather than at Oracle Park.

Oracle Park hosted Games 1 and 2 of the 2012 World Series on October 24 and 25. The Giants beat the Detroit Tigers twice, 8–3 and 2–0 respectively. The Giants would go on to win the 2012 World Series in a four-game sweep at Comerica Park.

On July 23, 2013, due to a previous rain-out in Cincinnati, Oracle Park served as the "home" venue of the Cincinnati Reds for the second game of a doubleheader against the Giants.[38] Giants manager Bruce Bochy won his 1,500th career game.

On June 25, 2014, Tim Lincecum pitched the 3rd no hitter at Oracle Park against the San Diego Padres in a 4-0 win. It was his 2nd no hitter of his career, with both of them coming against the Padres.

Oracle Park hosted Games 3, 4, and 5 of the 2014 World Series on October 24, 25, and 26. The Giants beat the Kansas City Royals 2 out of the 3 games played at Oracle Park, losing Game 3, 3–2, before winning Games 4 and 5, 11–4 and 5–0 respectively. They ultimately went on to win the series in seven games, with the clinching game played at Kauffman Stadium rather than at Oracle Park. As of 2017, the Giants have not hosted a World Series clincher at Oracle Park, but they did host two at Candlestick Park: the first being in 1962, which was won by the New York Yankees, and the second in 1989, which the Oakland Athletics won in a four-game sweep.

On June 15, 2015, the Giants set a record for most consecutive home losses at Oracle Park at nine straight games with a 5-1 loss to the Seattle Mariners. This losing streak was the Giants' longest since an 11-game home loss streak at the Polo Grounds in New York in 1940.[39]

From October 1, 2010 to July 18, 2017, Oracle Park recorded 530 consecutive sellouts, the second longest in Major League history behind Fenway Park's 794 consecutive sellouts from 2003 to 2013.

Giants Enterprises, a wholly owned subsidiary of the San Francisco Giants created and headed by longtime team executive Pat Gallagher, brings non-baseball events to Oracle Park on days when the Giants do not play. Prominent among these has been the usage of the stadium for football. It has also hosted a range of other sporting and musical events.

The Mavericks big-wave surfing contest is broadcast live on the giant video display at Oracle Park when the event is held. In 2006, the park hosted ICER AIR the first stadium big-air ski and snowboard competition to be held in the United States.

San Francisco Opera partnered with Giants Enterprises to do three broadcasts, most recently Tosca, in June and September 2009.
